MERLIN PERMEATE STORAGE SYSTEMS
The Merlin is designed to provide an average 1/2 gpm (1.89 Lpm)
continuous flow rate at NSF/ANSI 58 conditions. Some applications may
require an intermittent flow rate higher than the 1/2 gpm rate. This can be
accomplished by using a permeate storage tank.
Type Of Storage Tank
Pressurized storage tanks create a backpressure on the system that will
reduce performance. For this reason we recommend the use of an
atmospheric storage tank with a float shutoff for storing permeate water
as shown in Figure 13.

Mechanical float must trap and
hold permeate pressure or
Merlin will run to drain.
